President Barack Obama's approval rating has hit its highest point in two years – 60 percent – and more than half of Americans now say he deserves to be re-elected, according to an Associated Press-GfK poll taken after U.S. forces killed al-Qaida leader Osama bin Laden.

In worrisome signs for Republicans, the president's standing improved not just on foreign policy but also on the economy, and independent Americans – a key voting bloc in the November 2012 presidential election – caused the overall uptick in support by sliding back to Obama after fleeing for much of the past two years.

Comfortable majorities of the public now call Obama a strong leader who will keep America safe. Nearly three-fourths – 73 percent – also now say they are confident that Obama can effectively handle terrorist threats. And he improved his standing on Afghanistan, Iraq and the United States' relationships with other countries.

Despite a sluggish recovery from the Great Recession, 52 percent of Americans now approve of Obama's stewardship of the economy, giving him his best rating on that issue since the early days of his presidency; 52 percent also now like how he's handling the nation's stubbornly high 9 percent unemployment.

The economy remains Americans' top issue.
